I can tell by the end of the day, us fans are either going to be very happy or very sad. I want us to win the game, so Mou needs to tell his big boys to fly into tackles and bring the crowd volume up. City is just not playing against 11 men, they are also playing against the 75,000 fans inside the ground. So, I think at first, they will try to play their slow passing game to have a grip of the game and not get the OT crowd riled up too much. We must defend and not give them a inch of the space they love to have by flying into tackles and getting into their faces. This will help bring the atmosphere up at OT and City players will start getting nervous and losing the ball and we can counter attack with our players. We do have to look out for two players especially De Bryune and Silva, because if we can cut off De Bryune by having Herrera mark on him, we immediately cut off the link for Sterling and Sane to attack from the wings and Aguero to make those runs and receive the ball between the Central defenders. De Bryune does a couple of things well, he likes to play those one twos(the goal he scored against Chelsea) and he plays those beautiful passes to the wingers and also, he is also a good passer and crosser with the ball. I don't see him as much as a runner with the ball, or a dribbler. Silva is another one I see who makes those silky runs through the left channels in the penalty box where he is very dangerous, and he has good composure with the ball and is also a good dribbler so we need to watch out for that. He is everything I wish Mata was for us. If our defenders don't make any mistakes like Blind did in the last game against them at OT and even if the score is 0-0 at half time, we have a great opportunity of having really good chances later on in the game where we can score and I can imagine the City players will be much tired and feeling the effects of playing at OT(Similar to last season's game at OT against them).
Also, it is essential that our defenders don't start ball watching if De Bryune and Silva receive the ball, this is the same mistake all PL defenders do when they play against City this season. So I want us to be constantly aware of the runs Sterling and Sane will try to make behind our defenders.
